Smart home tech, weighed fairly.
Our Best Overall and Best Budget pick on every page, with the regular price we last saw, so you can tell a real Black Friday deal from a fake one.
Black Friday falls on November 27, 2026, and Cyber Monday on November 30. Smart home prices on Amazon usually start dropping the week before, especially Amazon's own Echo and Ring devices, Google Nest, and big brands like TP-Link and eufy. The trick is knowing what a device normally costs, so below is every one of our top picks with the regular price we captured. If the Black Friday price is lower, it's a real deal. If it isn't, wait or buy something else.
Black Friday: Friday, November 27, 2026. Cyber Monday: Monday, November 30, 2026. Early deals usually start the week before. Every button below opens the live Amazon listing, so you see today's price next to the regular price we recorded.

Black Friday is Friday, November 27, 2026, the day after Thanksgiving. Cyber Monday is November 30, 2026. Amazon usually starts early Black Friday pricing on smart home devices the week before.
Amazon's own devices (Echo speakers, Echo Show, Ring doorbells and cameras, Blink) usually see the deepest cuts, along with Google Nest and multi-pack smart plugs and bulbs. Niche Z-Wave and Zigbee gear rarely goes on sale, so buy it when you need it.
Black Friday week usually has the widest selection. Cyber Monday often repeats the same prices and adds a few. If your pick hits a price you're happy with, buy it, because popular bundles can sell out.
Bundles like a doorbell plus chime, or a camera plus an Echo Show, are often where the real savings are. Check that you'll use every piece; a bundle is only a deal if you wanted the extras.
